The most affected was secondaryflow losses for the energy loss distribution along the blade height, other losses along the distribution was average.
对于能量损失沿叶高分布影响最大的是二次流损失,其他损失沿叶高分布相对比较平均。

There are flow separations at the front blade of bulge tip clearance. The high speed area of groove tip clearance increases the secondaryflowloss dramatically.
凸型间隙在叶片前缘引起了流动分离,凹型间隙存在一高速区,增加了二次流损失。

The boundary layer thickness of the forward skewed rotor decreases in the top of blade due to reduction of the secondaryflowloss. This fact conforms with experimental investigation.
